fitPFm: fitPFm

In LuchTiarna/PsyMetFuns: Package for extrapolating psychometric information

Description

Provides the frame for psycometrics function models. Combines the sigmoid and core function.

Usage

fitPFm(formula, data, sigmoid, core, gamma = NULL, lambda = NULL,
  split_by = NULL, par = NULL, fn = NULL, gr = NULL,
  type = "hitPercentage", ..., method = c("Nelder-Mead", "BFGS", "CG",
  "L-BFGS-B", "SANN", "Brent"), lower = -Inf, upper = Inf,
  control = list(), hessian = FALSE)

Arguments

sigmoid	determines the sigmoid of the fuction
core	dermines the core of the function
gamma	sets the loves boundary of function
lambda	sets the highes boundary of function
type	specifies, whether function is CDF of PDF type
...	specifies the parametres or core function
x	the vector of level values
inverse	specifies, whether to compute the inverse function

Value

vector of return values
